Buoyant raft and method of construction

ABSTRACT

A raft comprises a core comprising a buoyant material. The core has a generally flat deck surface, a generally flat hull surface, and a height defining a bow surface, a stern surface, a starboard surface and a port surface. The deck surface and the hull surface have substantially equal widths. The deck surface further has a length being greater than a length of the hull surface in which a difference of the length of the deck surface and the length of the hull surface determines a curvature of the bow surface and a curvature of the stern surface. A coating is applied to the core in which the coating encapsulates the core, and is operable for mitigating damage to the core and entry of water into the core.

FIELD OF THE INVENTION

One or more embodiments of the invention generally relate to buoyant rafts. More particularly, the invention relates to methods of constructing buoyant rafts.

BACKGROUND OF THE INVENTION

The following background information may present examples of specific aspects of the prior art (e.g., without limitation, approaches, facts, or common wisdom) that, while expected to be helpful to further educate the reader as to additional aspects of the prior art, is not to be construed as limiting the present invention, or any embodiments thereof, to anything stated or implied therein or inferred thereupon.

Currently available buoyant rafts may not provide a sufficiently multipurpose, lightweight, compact, durable, non-inflatable, substantially flat-surfaced product which may not take on water.

The following is an example of a specific aspect in the prior art that, while expected to be helpful to further educate the reader as to additional aspects of the prior art, is not to be construed as limiting the present invention, or any embodiments thereof, to anything stated or implied therein or inferred thereupon. One such aspect of the prior art shows a device for supporting a person lying down. By way of educational background, another aspect of the prior art generally useful to be aware of teaches of a fishing boat which has two pontoons connected by a panel. Yet another such aspect of the prior art discloses of a fishing apparatus comprising a floating body on which a sail is mounted in a plane substantially perpendicular and transvers of the longitudinal centerline of the floating body. However, these available solutions may not be sufficiently effective. A solution which provided an effective method for constructing and/or means for using a multipurpose, lightweight, compact, durable, non-inflatable, substantially flat-surfaced raft would be desirable.

In view of the foregoing, it is clear that these traditional techniques are not perfect and leave room for more optimal approaches.

Some embodiments may provide means and/or methods for construction of a buoyant raft.

FIGS. 1A, 1B, and 1C illustrate an exemplary core 100 of a buoyant raft, in accordance with an embodiment of the present invention. In the present embodiment, FIG. 1A illustrates a top view of a core 100, FIG. 1B illustrates a side view of a core 100, and FIG. 1C illustrates a bottom view of a core 100. In some embodiments, a buoyant raft may be substantially composed of a core 100. In some embodiments, a core 100 may have multiple sides, including, without limitation, hull 105, deck 110, bow 115, stern 120, starboard 125, and port 130. In some alternative embodiments, a core 100 may have additional sides. In other alternative embodiments, a core 100 may have only one, two, or more distinguishable sides due to a lack of defined edges between sections of core 100. A coating 140 encapsulates the core 100.

FIG. 2 is an illustration of an exemplary method for constructing a core from a single piece of material, in accordance with an embodiment of the present invention. In the present embodiment, one may determine one or more portions of material which may constitute one or more sides of core 100 in a step 205. In a non-limiting example, one may determine that one portion of a piece of material may be made to be a deck and another portion of the piece of material may be made to be a hull. In the present embodiment, one may determine whether one has means for cutting or fabricating single piece of material to desired dimensions in a step 210. In some embodiments, any dimensions may be suitable desired dimensions. In a non-limiting example, suitable dimensions may be 4 ft (bow 115/stern 120)×8 ft (starboard 125/port 130)×6 in. (height), as well as a curvature of bow 115/stern 120 areas. In the present embodiment, if one has means for cutting single piece of material to desired dimensions, one may cut material to desired dimensions in a step 215. Further, in the present embodiment, one may otherwise cut material to rough dimensions in a step 220. In some embodiments, rough dimensions may be any dimensions which may be one's best available approximation of exact dimensions. In the present embodiment, one may shape material to meet desired dimensions in a step 225. In some embodiments, one may print the entire raft in a three dimensional printer in a step 230. In many embodiments, one may encapsulate buoyant raft in a step 235 with any suitable coating, including, without limitation, composite coating, spray/brush/roll-on polyurea, graphine, high density polystylene, fiberglass, fiber-reinforced-polymers, nanomaterials, carbon-fiber-reinforced-polymers, ceramics, and rubber.

FIG. 3 is an illustration of an exemplary method for constructing a core from multiple sheets of material, in accordance with an embodiment of the present invention. In the present embodiment, one may adhere sheets together in a step 305. In some embodiments, one may use any suitable adhering means. In the present embodiment, one may shape material to meet desired dimensions in a step 310. In many embodiments, one may encapsulate buoyant raft in a step 335 with any suitable coating, including, without limitation, composite coating, spray/brush/roll-on polyurea, graphine, high density polystylene, fiberglass, fiber-reinforced-polymers, nanomaterials, carbon-fiber-reinforced-polymers, ceramics, and rubber.

In some embodiments, core 100 may be composed of any suitable material, including, without limitation, extruded polystyrene foam and expanding marine polyurethane foam, aerogel, Airloy™, expanded polystyrene, spray foam, closed-cell-foam, polyisocyanurate, cross linked PE foam, plastic foam, polymers, and carbon. In some of these embodiments, material may have 1.3-pound density.

FIG. 4 is an illustration of an exemplary method for constructing a core from expanding marine polyurethane foam, in accordance with an embodiment of the present invention. In the present embodiment, one may pour foam into a preformed mold with in a step 405. Further, in the present embodiment, one may determine whether preformed mold meets desired dimensions in a step 410. In the present embodiment, if preformed mold does not meet desired dimensions, one may shape material to desired dimensions in a step 415. In many embodiments, one may encapsulate buoyant raft in a step 435 with any suitable coating, including, without limitation, composite coating, spray/brush/roll-on polyurea, graphine, high density polystylene, fiberglass, fiber-reinforced-polymers, nanomaterials, carbon-fiber-reinforced-polymers, ceramics, and rubber.

FIG. 5 is a photograph of an exemplary core 100 which has been situated in a jig, in accordance with an embodiment of the present invention. In the present embodiment, one may place a core 100 into a jig 505 to allow for efficient shaping of the core 100. Further, in the present embodiment, one may place the core 100 having a hull 105 facing upward. In some embodiments, one may place jigs 505 on multiple sides of a core 100. In some of these embodiments, one may cut the core 100 along a jig pattern 510. In many embodiments, one may use any suitable means of cutting, including, without limitation, a hot wire, laser, band saw, hot knife, high pressure fluid, hand saw, power saw, etc. In some embodiments, one may smooth a surface of a core 100 by using any suitable means, including, without limitation, sandpaper.

FIG. 6 is an illustration of an exemplary means for cutting a core 100, in accordance with an embodiment of the present invention. In the present embodiment, one may use a cutting utensil to cut off portions of a core 100 piece-by-piece to form a curvature. In a non-limiting example, a cutting utensil having a length greater than 8in. may be suitable to bridge a width of a core 100. In a non-limiting example, when cutting from 605 to the other 605 the width would be the distance between point 615 and 620, hence the cutting utensil greater than 8 in. In some embodiments, one may use a writing utensil to mark a desired curvature based on a jig pattern 510 prior to using a cutting utensil. In the present embodiment, one may draw mirrored sets of lines 605 to form a plane 610 which may provide a basis to follow with a cutting utensil. In a non-limiting example, one may use planes 610 as a basis when one may not have a cutting means large enough to span an entire width of a core 100. In the present embodiment, cutting from one point 615 to a second point 620 may create a triangular prism shaped piece of core 100 material which may be removed. In many embodiments, one may smooth out undesirable edges using sandpaper or other means.

In some embodiments, one may make one or more holes 135 in a core 100. In some embodiments, one or more holes 135 may extend entirely from one side of a core 100 to another side of the core 100. In other embodiments, one or more holes 135 may extend any distance into a core 100. In a non-limiting example, one may make 12 holes 135 in a core 100. In an exemplary embodiment illustrated by FIG. 1, points marked with an “X”, “Y”, and “Z” may signify holes. In the present non-limiting embodiment, each hole 135 may be situated 31.25 in. from a bow 115 or stern 120 side. As a non-limiting example, practical considerations for hole placement may include, but are not limited to, the style of seat used, the style of fishing pole holder used, the style of rope cleat used, or the style, function, ease of use of any other hardware installation. A second practical consideration may be the structural limitations of the core material. A third practical consideration may be the distribution of mass of the raft's load in relation to the center of mass of the raft. Basically, one may consider what the holes are intended for and how the hardware, or the use of the hardware, will eventually affect the list or pitch or the raft. Further, in the present non-limiting embodiment, eight holes marked with “X” and “Z” may signify holes 135 which may extend entirely from a deck 110 side to a hull 105 side and may be 5/32 in. in diameter. In a non-limiting example, these holes 135 may be receive rope cleats and/or loops for safety lines for securing equipment. In the present non-limiting embodiment, four holes 135 marked with “Y” may extend a depth of 4.75 in. from the hull 105 side and may be 0.5 in. in diameter. In a non-limiting example, these holes 135 may receive fishing rod holders. As a non-limiting example practical considerations for hole depth and diameter include, but are not limited to, the style of hardware installed, the core's material property limitations, aesthetics, and necessity.

FIG. 7 is an illustration of exemplary method for inserting one or more fishing rod holders into a buoyant raft, in accordance with an embodiment of the present invention. In the present embodiment, one may inject caulking 145 into a desired hole 135 in a step 705. In some embodiments, one may use any suitable caulking, including, without limitation, silicone caulking In a non-limiting example, one may inject 4-5 ml of silicone caulking into a hole 135. Practical considerations for the amount of caulking 145 include but are not limits to the volume of the void between the core 100 and the hardware being installed. In the present embodiment, one may insert a rod holder receiver into the hole 135 in a step 710. In some embodiments, rod holder receive may protrude any distance from the buoyant raft.

In some embodiments, one may level and/or fill any flaws (e.g. dents, cracks, gaps, or unwanted protrusions) in buoyant raft's core 100. In many embodiments, one may encapsulate buoyant raft in any suitable coating, including, without limitation, composite coating, spray/brush/roll-on polyurea, graphine, high density polystylene, fiberglass, fiber-reinforced-polymers, nanomaterials, carbon-fiber-reinforced-polymers, ceramics, and rubber.

In at least one embodiment, a raft may have a built-in transom and/or a detachable transom. In other embodiments, a raft may have one or more cavities which may be designed to provide buoyancy.

In many embodiments, one may install hardware into one or more holes 135. In some embodiments, one may install any suitable hardware, including, without limitation, anchoring hardware. In some of these embodiments, anchor may be installed so as to be flush with core 100 surface. In a non-limiting example, one may create a flush connection between an anchor and a core 100 surface by means oft-nuts and/or threaded hardware. In another non-limiting example, one may recess 6-inch fiberglass cylinders into core 100 surface. In the present non-limiting example, the fiberglass cylinders may be parallel with hull 105 of core 100 and cable ties may wrap around cylinders for securing purposes. In some embodiments, one may cut a recess of any suitable size into core 100 to form a receptacle for a securing means. In a non-limiting example, one may cut a triangular prism-shaped recess into hull 105, the recess being 6.25 in.×1.625 in. Practical considerations for the receptacle recess dimensions include the hardware's dimensions being housed and the physical properties of the core and the hardware.

Optimal dimensions provide sufficient surface area contact between the core and the hardware to at least support the expected force per unit area.

In some embodiments, a foam raft with a tough coating may be desirable so that it is light enough for one to carry, tough enough to withstand abrasions from barnacles, and small enough to fit in confined areas. In some embodiments, an added desired feature may include a small lip around the deck's edge of the raft to help keep any gear from sliding over the deck. In some embodiments the additional hardware (rope cleats, pole holder receivers, and safety line) may not be desired for the intended application.

In some embodiments, anglers that are looking for a way to get off the shoreline without having to make a major investment, nor settle for a heavy, narrow, unstable, or confining buoyancy device may find the raft to be the perfect buoyancy device to comfortably escape the landscape and fish that sought after location. Additionally with the pole holder receivers anglers can fish hands free with one or more poles.

Bow-Fishing is growing in popularity and is becoming legal on more and more waters. A problem that most small watercraft owners have though is stability. To more easily spot and get a shot at a fish the greater the angle of incidence should be for the bow-fisher. Therefore, standing on or sitting high on the watercraft is desirable. Also taking onboard a stuck fish can be chaotic. This may be a good reason to have your seat/s attached to a safety line not to mention unforeseen waves. In some embodiments, safety lines may be attached using holes 135.

Hunting involves a lot of waiting for the perfect opportunity. Sitting on a raft with seats makes the wait more enjoyable. In some embodiments, the pole holder receivers can double for anchor points for blind frame/s and material/s to help keep the hunter camouflaged.

In some embodiments, a swim platform or island may be made with one raft, or more than one raft connected, to provide an area of buoyancy. In some embodiments, the present invention may be used for, but not limited to, surfing, sailing, paddling, propelling, flotation, etc.

In some alternative embodiments, raft may be equipped with a motor or other means of propelling the raft.

Those skilled in the art will readily recognize, in light of and in accordance with the teachings of the present invention, that any of the foregoing steps may be suitably replaced, reordered, removed and additional steps may be inserted depending upon the needs of the particular application. Moreover, the prescribed method steps of the foregoing embodiments may be implemented using any physical and/or hardware system that those skilled in the art will readily know is suitable in light of the foregoing teachings. For any method steps described in the present application that can be carried out on a computing machine, a typical computer system can, when appropriately configured or designed, serve as a computer system in which those aspects of the invention may be embodied. Thus, the present invention is not limited to any particular tangible means of implementation.

All the features disclosed in this specification, including any accompanying abstract and drawings, may be replaced by alternative features serving the same, equivalent or similar purpose, unless expressly stated otherwise. Thus, unless expressly stated otherwise, each feature disclosed is one example only of a generic series of equivalent or similar features.

It is noted that according to USA law 35 USC §112 (1), all claims must be supported by sufficient disclosure in the present patent specification, and any material known to those skilled in the art need not be explicitly disclosed. However, 35 USC §112 (6) requires that structures corresponding to functional limitations interpreted under 35 USC §112 (6) must be explicitly disclosed in the patent specification. Moreover, the USPTO's Examination policy of initially treating and searching prior art under the broadest interpretation of a “mean for” claim limitation implies that the broadest initial search on 112(6) functional limitation would have to be conducted to support a legally valid Examination on that USPTO policy for broadest interpretation of “mean for” claims. Accordingly, the USPTO will have discovered a multiplicity of prior art documents including disclosure of specific structures and elements which are suitable to act as corresponding structures to satisfy all functional limitations in the below claims that are interpreted under 35 USC §112 (6) when such corresponding structures are not explicitly disclosed in the foregoing patent specification. Therefore, for any invention element(s)/structure(s) corresponding to functional claim limitation(s), in the below claims interpreted under 35 USC §112 (6), which is/are not explicitly disclosed in the foregoing patent specification, yet do exist in the patent and/or non-patent documents found during the course of USPTO searching, Applicant(s) incorporate all such functionally corresponding structures and related enabling material herein by reference for the purpose of providing explicit structures that implement the functional means claimed. Applicant(s) request(s) that fact finders during any claims construction proceedings and/or examination of patent allowability properly identify and incorporate only the portions of each of these documents discovered during the broadest interpretation search of 35 USC §112 (6) limitation, which exist in at least one of the patent and/or non-patent documents found during the course of normal USPTO searching and or supplied to the USPTO during prosecution. Applicant(s) also incorporate by reference the bibliographic citation information to identify all such documents comprising functionally corresponding structures and related enabling material as listed in any PTO Form-892 or likewise any information disclosure statements (IDS) entered into the present patent application by the USPTO or Applicant(s) or any 3rd parties. Applicant(s) also reserve its right to later amend the present application to explicitly include citations to such documents and/or explicitly include the functionally corresponding structures which were incorporate by reference above.

Thus, for any invention element(s)/structure(s) corresponding to functional claim limitation(s), in the below claims, that are interpreted under 35 USC §112 (6), which is/are not explicitly disclosed in the foregoing patent specification, Applicant(s) have explicitly prescribed which documents and material to include the otherwise missing disclosure, and have prescribed exactly which portions of such patent and/or non-patent documents should be incorporated by such reference for the purpose of satisfying the disclosure requirements of 35 USC §112 (6). Applicant(s) note that all the identified documents above which are incorporated by reference to satisfy 35 USC §112 (6) necessarily have a filing and/or publication date prior to that of the instant application, and thus are valid prior documents to incorporated by reference in the instant application.

Having fully described at least one embodiment of the present invention, other equivalent or alternative methods of implementing buoyant rafts according to the present invention will be apparent to those skilled in the art. Various aspects of the invention have been described above by way of illustration, and the specific embodiments disclosed are not intended to limit the invention to the particular forms disclosed. The particular implementation of the buoyant rafts may vary depending upon the particular context or application. By way of example, and not limitation, the buoyant rafts described in the foregoing were principally directed to method of construction implementations; however, similar techniques may instead be applied to method of use, which implementations of the present invention are contemplated as within the scope of the present invention. The invention is thus to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the following claims. It is to be further understood that not all of the disclosed embodiments in the foregoing specification will necessarily satisfy or achieve each of the objects, advantages, or improvements described in the foregoing specification.

Claim elements and steps herein may have been numbered and/or lettered solely as an aid in readability and understanding. Any such numbering and lettering in itself is not intended to and should not be taken to indicate the ordering of elements and/or steps in the claims.

The corresponding structures, materials, acts, and equivalents of all means or step plus function elements in the claims below are intended to include any structure, material, or act for performing the function in combination with other claimed elements as specifically claimed.

The Abstract is provided to comply with 37 C.F.R. Section 1.72(b) requiring an abstract that will allow the reader to ascertain the nature and gist of the technical disclosure.
